l claim as my invention:

:1. A lamp comprising a casing and a rerear of the casing having al'ined apertures, an anchoring alined apertures and equipped at each end Wit-ha groove, e5 tively entered u reflector andthe casing,and a lamp socket having its shell housed by and clarnped to the said tube. 2. ln a lamp, a casing having a domeshaped rear end, a reflector disposed Within the casingand having its edge engaging the interior of the said dome-shaped end, the reflector .and the said end having axial apertures, an anchoringtube coaxial with the said apertures `and interlocked at. its ends respectively with the said end and reflector,` and a completelainp socket having its shell housed .by the anchoring tube and flared over the forward end if the latter and having ane( other A portion engaging the rear end of 'the anchoring tube. C j

3.111 a lamp, a casing having a forwardly Vconceived back, a reflector housed by thc oasing and less concave than the said back and flector housed thereby, the reflector and the tube extending through the saidv the said groove being respeoby the aperturevvalls of the.

having itsl peripheral portion rearwardly bearing agalnst the interior of the casing, the said reliector ahd back having alined arial apertures, a lamp socket. disposed axial of the reflector and casing and extendingr through the said apertures and a mounting for the lamp socket including a tube housing the shell of the socket andertending through the said apertures and having its ends respecti'vely spun over the forward face of the reflector and the rear of the said bach.

e, ln combination, a lamp casing, a reflector disposed therein and having its central portion spaced from the baclro the oasing, the said-back and reflector having-'an anu choring tube extending through the said perorations and interloclred at its ends res 3ectively with the said baelr and reflector to rigidly space the same, and a lamp-socket having its shell housed by the said tube and flared at its forward end over the forward end of the said tube, the socket including an insulating body anchored to the socket shell and having an annular shoulder engaging the rear end oit the said tube.

5. lln combination, a lamp casing, a reflector disposed therein and having its central portion spaced from the back or' the casing, the said back and reflector having alined perforations, an anchoring tube extending through the said perorations and secured to both said back and reflector, and a lampsoclret extending through the said tube and including a shell and an insulator fastened thereto, the socket shell being formed for engaging the said tube to prevent rearward movement Within the latter and the insulator being formed for engaging the rear end. of the tube to prevent forward movement of the socket.
